Eventually the timer will get a few interrupts, but it can stay at the same spot for a long time. If I reboot, and then add append=noapic in lilo and reboot again I never get a problem in the future. One of the boxes I have has a third NIC and if I use noapic the machine cannot boot. Is there something besides noapic I should try. Is there any other information you would like? jlogan@x306:~$ cat /proc/interrupts CPU0 CPU1 0: 4604125 0 IO-APIC-edge timer 1: 9 0 IO-APIC-edge i8042 9: 0 0 IO-APIC-level acpi 14: 2 0 IO-APIC-edge libata 15: 1679925 0 IO-APIC-edge libata 16: 0 0 IO-APIC-level uhci_hcd 18: 12672 0 IO-APIC-level eth0 19: 0 0 IO-APIC-level uhci_hcd 23: 0 0 IO-APIC-level ehci_hcd NMI: 0 0 LOC: 4604073 4604079 ERR: 0 MIS: 0 Later, JOSH - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
